Towbar/Base Plate Questions

I have found a used Roadmaster Sterling Tow Bar. My plan is to purchase a baselplate for my Explorer Sport Trac. Which baselplate would be compatible with this older tow bar??? I am planning on staying with Roadmaster with regards to the baseplate.
Thanks in advance for your suggestions.

Roadmaster tow bar Roadmaster base plate, Simply go to the Roadmaster and find the proper baseplate there. It depends both on the tow bar and the towed car.

You can contact the company, give them the year, make and model of both the tow bar (or a photo) and of the towed car and they will get back to you.

I was told you must use a base plate from the same manufacture as the tow bar. They need to match. There might be exceptions, but that was the rule I was told.

And, the tow bar angle cannot exceed 4" high or low. If it's too low (angle downward force to hitch, Toad is high), you're toad front end may lift up when braking.

If the angle from the toad to the RV hitch is too high (Toad is low), you're toad forces the RV hitch up when braking and forces the toad front end down.

This is a serious condition. Use a 2" or 4" or more drop/rise to adjust the level of the tow bar so it does not exceed a greater than 4" rise or fall.

They make adapters to connect Roadmaster to Blue Ox vice versa and others. I currently have Blue Ox baseplate and Roadmaster Falcon 2 towbar.

According to Blue Ox, the toad end of the towbar should be level with the RV, down to no more than 4" below the RV end. It should never be higher than the RV end.

Be aware that only the 4WD Explorers can be towed four-down, and those require a Neutral Tow kit that is no longer available - you may have to custom make one.

The Roadmaster website will give you the base plates numbers for your car - they will work with the Sterling tow bar.

I am buying an FWD Ford 2011 explorer and both the FWD and the AWD can be towed four down without any adapter. I'm not sure which year your are referencing.
